GEORGE P. CLARK, OF JAMAICA PLAIN, MASSACHUSETTS, ASSIGNOB, BY MESNE ASSIGNMENTS, TO UNITED SHOE 1VIACI-IINERY CORPORATION, OF PATERSON. NEW JERSEY, A CORPORATION OF NEVJ JERSEY.

EYELET-SETTING MACHINE.

To all whom it may concern:

Be it known that I, GEORGE P. CLARK, a citizen of the United States, residing at Jamaica Plain, in the county of Sufiolk and State of hlassachusetts, have invented certain Improvements in Eyelet-Setting Machines, of which the following description, in connection with the accompanying drawings is a specification, like reference characters on the drawing indicating like parts in the several figures.

This invention relates to machines for setting eyelets or other fastening devices in sheet material and more particularly to machines for setting blind or invisible eyelets in the uppers of boots and shoes.

In setting invisible eyelets in a shoe upper the outer and lining parts of the upper are perforated and the eyelets are set in the lining part in register with the holes in the In setting blind eyelets the operation is reversed and the eyelets are set in the outer part of the upper in register with holes punched through the lining part. An object of the present invention is to provide a machine by which the operations incident to setting either blind or invisible eyelets may becarried out with improved accuracy and despatch. An important feature of the invention consists in a movable head carrying a cooperating punch and punching die. said punch and die being relatively movable to perforate the work and then movable with the head to feed the work. This construction is advantageous in that a particularly clean cut hole is formed in the outer part of the upper so that a pleasing appearance is imparted to the upper. I

As herein shown, the punch is arranged to pass entirely through the punching die and to cooperate with a stationary cutting block in perforating the lining part of the upper. Th s arrangement constitutes another feature of the invention which it is believed is hroadlv novel.

These and other features of the invention will be best understood and appreciated from the following description of a pre- Specification of Letters Patent.

Application filed February 2, 1916. Serial No. 75,829.

ferred embodiment thereof selected for purposes of illustration and shown in-the accompanying drawings, in which,

Figure 1 is a perspective view of portions of an eyeleting machine having the present invention embodied therein;

Figs. 2 to 5 show the punching and setting tools in the successive positions occupied by them during the cycle of the machine;

Fig. 6 is a plan view showing the position of the upsetting die in an upper;

Fig. 7 is a view in perspective of the upsetting die.

The invention is herein disclosed as embodied in the machine of an application of P. R. Glass, Serial No. 855,185, filed August 5, 1914. Such parts of the machine as are not herein shown may be of the same construction as corresponding parts illustrated in said application. It will be understood, however, that the invention is not limited in its application to this or to any particular type of eyeleting machine.

The frame 10 is provided with two pair of horizontal hearings in the upper of which is received a stationary guide rod 1:2 and in the lower of which slides a movable guide rod 14. A transversely movable head 16, slides upon the upper rod 12 and is fast to the lower rod 14;. The movement of the head 16 is thus limited to a horizontal path.

The head 16 is provided with vertical bear ings for a plunger 18 carrying at its lower end a cylindrical tubular punch 21. The plunger is reciprocated vertically by an eccentric and other mechanism not herein shown. In the lower portion of the frame are provided bearings for a vertically movable plunger having at its upper end the lower or eyelet insertingdie 40 and a center spindle 42 for picking successive eyelets from a raceway 38. The inserting die 10 is arranged to pass through an opening in a stationary work plate 34 which is mounted upon the machine frame. The parts of the machine thus far described. with the exception of the punch, are similar to the corresponding parts of the machine of the application above identified.

n as" of the frame are swung apar and slipped off of their journals. in the lower side of the frame A is horizontally dise L bar 28 carrying at its inner end an nos 1 i l ui'settlng die 52 racing downwardly. Zhe

end or the to the table. The 1 engage the worl: bar but will not the bar.

bar 28 is of yielding character and, in order to adjust tie vertical position oi: the upsetting lie, there is proyided an ad ust ing bolt 30 by w ich the inner end ot the bar 28 may be raised or lowered. The inner end the bar is formed with an opening which co: .'tut.es a punching die to cooperate with tne cylindrical punch The punching die opening, shown 1g. 7, passes through the center of the upsetting die 32. A stationary cutting block 35 is secured to the frame ir an opening formed in the work table 3% anl is located in alinem'ent with and ben n the punch when the latter occupies its i i ial position. The construction and arran enient of these iarts is such that the punci 21 may pass entirely through the ope; ing in the punching die and cooperate with the cutting blocl: 35 to perforate work located beneath the punching die.

i i presser foot 36 is pro ed to clamp the work to the work table during the re verse movement the head 16. The presser is irorided with an which extends the work t thererore will iposite sides of the -o uorlr ainst J izjisible eyelets in a shoe upper the upper presented to the nutchine with its outer or le' "her part 50 above the bar 28 and with its g part on the cutting block beneath the end of the bar. In handling a right quarter the frame 24:

swung toward the right 'side of the 111:;- chine as this trcilitates reaching the point at which it is desired to set the uppermosteyelet. The position of the bar 28 which carries the upsetting die is shown in Fig. 6. Haring presented the upper, the machine is set in operation whereupon the plunger 18 ii per is perforated by L l n which tacres place n the outer surface of the punch 21 i die. punch 21 passes the punching die and ting bloclr 35. Fig. 3 illustrates the punch in this position. The plunger 20 is then elevated slightly to release the )ressuro on the cutting block 35 and the head 16 moved toward the left, thus feeding the hole in the upper into alinement with and above the eyelet inserting tool 40. This position oi the tool is illustrated in Fig. 4. The lower plunger has been meanwhi e elevated sufficiently to pass the spindle through the endrnost eyelet in the raceway 38 and the raceway has been retracted leaving the eyelet in place upon the set 40. In the next step of the cycle the upper plunger 18 is depressed and the inserting die is elevated forcing the eye-let barrel through the hole in the lining part of the upper and clenching it against the upsetting die 32. The punch 21 at the same time is depressed sutficiently to bring its shoulder against the surface of the outer part or" the upper so as to reinforce the bar 28 against the pressure '01"- the inserting die. 111 this operation the punch 21 which is of the "nine. diameter as the spindle 42 forces the spindle downwardly into the inserting die.

During the feeding operation the presser foot 36 is lifted but at the conclusion of the setting operation thep'resser foot is lowered to hold the work stationary upon the work plate 3%. The plunger 18 is then lifted, the lower plunger 39 depressed and the head 16 and its associated parts returned toward the right to initial position.

in setting blind eyelets the operation is the swe t above described except that the upper is presented to the machine with the lining side uppermost, or in a position rev ed ironi that shown in Fig. GJ moving thus described rhy invention, 1 claim as new and desire to secure by Letters Fatei'itz 1.
